SAN ANTONIO, Texas—In an apparent violation of state law, Battleground Texas officials are exploiting legally protected information to turn voters out to the polls as part of the Democratic party’s quest to paint the Lone Star State blue, a new undercover video from James O’Keefe reveals.

The footage shows Battleground Texas volunteer Jennifer Longoria saying the group uses the phone numbers from voter registration forms in later efforts to boost turnout on election day.

Texas Election Code prohibits the use of, or even the copying of, phone numbers provided by individuals registering to vote.

“Every time we register somebody to vote, we keep their name, address, phone number,” Longoria said.
